  When the input device 103 does not accept the scale designation from the operator after connection to the recording medium 108 in order to search for desired music data from the music data stored in the recording medium 108 connected to the list item search device The list scale is 1/1 and is displayed on the list scale 403. As shown in FIG. 4, the list display screen 401 displays the music data read from the recording medium 108 in a predetermined order. Are arranged and displayed. Next, processing performed by the list item search device will be described.

  FIG. 5 is a flowchart showing the processing procedure of the list item display processing performed when the control unit 101 receives a signal for reducing or expanding the scale of the list. Hereinafter, the list item search method of the present embodiment will be described with reference to the flowchart of FIG.

  An example will be described in which the music data displayed on the list display screen unit 401 is No. 1 to No. 5 in FIG. 4 and the desired music data that the user wants to search is No. 303. It is assumed that the user understands only the title of the desired music data.

  Since the desired music data is not displayed on the list display screen unit 401, the user presses the reduction instruction button 404 or traces the list display screen unit 401 with two fingers. When the reduction instruction button 404 is pressed or the list display screen unit 401 is traced with two fingers, the input device 103 accepts the operation and transmits a reduction instruction signal to the control unit 101. The control unit 101 receives the signal (step 501), and determines whether the received signal is a reduction instruction signal or an enlargement instruction signal (step 502).

  If the control unit 101 determines that the reduction instruction signal has been received, the control unit 101 determines whether or not the current list scale is the minimum value in the scale list FIG. 2 and confirms it (step 503). When the control unit 101 determines that the current scale is the minimum value and 1/500 of the scale list in FIG. 2 (step 503; Yes), the control unit 101 proceeds to step 509 because no further reduction is possible.

On the other hand, when it is determined that the current scale is not the minimum value and 1/500 of the scale list in FIG. 2 (step 503; No), the control unit 101 changes the current scale to the scale designated by the reduction instruction signal. (Step 505)
When the current scale is changed, if the list item is selected from the music data list shown in FIG. 4, the control unit 101 starts with the selected item in accordance with the scale after the change. If the list item is not selected, any list item is displayed according to the scale after the change, centering on the first item of the displayed list item. A predetermined reduced list item is obtained by thinning out an arbitrary number of list items at intervals (step 507). For example, as shown in FIG. 6, when the scale is changed from 1/1 to 1/100 while the user is selecting No2, the acquired list items are No2, 102, 202, 302, 402. .

  That is, the control unit 101 thins out the list items from No3 to No101 other than the selected No2 among the list items from No2 to No101 according to the scale change degree (reduction degree) (that is, every 100 items). In addition, the list item of the next No102 is displayed, and among the list items No102 to No201, the list items No103 to No201 other than the displayed No102 are set to the scale change degree (reduction degree). Thin out together. Thereafter, similarly, the reduced list is displayed by repeating the number of list items. The control unit 101 stores the thinned list items in the internal storage unit 1041 in preparation for receiving an enlargement instruction signal thereafter.

  After acquiring the list thinned out at the scale after the change, the control unit 101 transmits a display instruction signal to the display device 102 in order to display the acquired list items on the display unit 401. FIG. 6 shows an example of the list display screen when the scale is changed to 1/100 while the user selects No. 2 music data. The list after the reduction is scrolled by operating the scroll bar 406. Make it possible.

  From the list display screen of FIG. 6, the user selects the item No. 302 that is close to the song name of the desired music data and presses the enlargement instruction button 405, or two fingers centering on No. 302 on the list display screen unit 401. Trace as if spreading. When the enlargement instruction button 405 is pressed or the list display screen unit 401 is traced so as to be spread with two fingers, the input device 103 accepts the operation, and an enlargement instruction signal is transmitted to the control unit 101. The control unit 101 receives the signal (step 501), and determines whether the received signal is a reduction instruction signal or an enlargement instruction signal (step 502).

  When the control unit 101 determines that the enlargement instruction signal has been received, the control unit 101 determines whether or not the current list scale is the maximum value in the scale list FIG. 2 and confirms it (step 504). If the control unit 101 determines that the current scale is the minimum value and 1/1 of the scale list in FIG. 2 (step 504; Yes), the control unit 101 proceeds to step 509 because no further enlargement is possible.

  On the other hand, if the control unit 101 determines that the current scale is not the maximum value and 1/1 of the scale list in FIG. 2 (step 504; No), the control unit 101 changes the current scale to the scale indicated by the enlargement instruction signal ( Step 505).

  When the list item is thinned out, the control unit 101 refers to the list item stored in the internal storage unit 1041, and when the current scale is changed, the list item is selected from the music data list in FIG. The list item is selected by returning the number of list items at the interval between any list items according to the scale after the change, starting with the selected item and returning any number of list items. If not, return the specified number of list items by returning any number of list items at the interval between any list items according to the scale after the change. Obtain (step 507). For example, as illustrated in FIG. 7, when the scale is changed from 1/100 to 1/10 while the user is selecting No2, the acquired list items are No2, 22, 32, 42, 52. .

  That is, the control unit 101 returns the list items from No3 to No21 other than the selected No2 among the list items from No2 to No402 according to the scale change degree (enlargement degree) (that is, 10 items). Then, the list item of the next No22 is displayed, and among the list items of No22 to No31, the list items No23 to No31 other than No22 being displayed are changed in scale (degree of enlargement). ) To restore every 10 pieces. Thereafter, similarly, the enlarged list is displayed by repeating the number of list items. If the user selects No. 302 and changes the scale to 1/1, the items displayed on the list display screen unit 401 are displayed as No. 302, 303, 304, 305, 306... Is done.

  Then, the control unit 101 determines whether or not desired music data (song) has been specified (step 509). When it is determined that a song has not been specified (step 509; No), the control unit 101 returns to step 502. If it is determined that the desired music data has been specified by repeating the processing of steps 502 to 508 (step 509; Yes), the desired music data No. 303 is displayed on the list display screen unit 401. Then, the user selects the music data of No. 303, ends the search, and reproduces the music of the selected music data.

  As described above, in this embodiment, when searching for a list item, the interval between the list items is changed according to the designated scale, and an arbitrary number of list items can be thinned and displayed. Since it is possible, music data at the back of the list can be selected with a simple operation. Moreover, since the list items can be displayed from the upper part to the lower part by thinning and displaying, it is possible to select by simple operation when searching the music data in the middle part of the list. As described above, by performing the above-described processing, a huge number of music data arranged in a predetermined order can be thinned out and displayed in a list with a simple operation, and the position of desired music data can be easily estimated. , And the search time can be shortened.

  In the above embodiment, the item search method of the present invention is applied to the search of car audio music data. However, the present invention is not limited to this, and many other items are searched. Needless to say, this can be applied to.
